APPARATUS FOR ENRICHING iLLUNilNATlNG-GAS.

SPECIFICATION inning part of Letters Patent No. 355,5 26, dated January4., 1887.

Application filed June 21,186.

To LZZ whom, it mag/'colmena' Be it known that I, FREDERICK B. STRUNZ, acitizen ofthe United States, residing at Pitts burg, in the county ofAllegheny and State. of Pennsylvania, have invented new and usefulImprovements in Apparatus for Enriching Illuminating-Gas, of which thefollowing is a speciiication.

My invention relates to apparatus for en riching illuminating-gas bybringing it, while heated, into contact with a volatile hydrocarbon, bywhich the gas is caused to take up a certain percentage of thevolatilized material.

The purpose of my invention is to provide 'an extremely simple, compact,and easily-operated device whereby this purpose may be effected; and itconsists in the several novel features of construction andcombinations-of parts hereinafter fully set forth, and definitelypointed outin the claim annexed to this speciiication. f

In the accompanying drawings, Figure l is a vertical central section ofan apparatus con- Fig. 2 is a side elevation of the same in operation.

In the said drawings, the reference-numeral l designates the gas-supplypipe, which may.

be the stem of any ordinary gasbracket. Upon this stem is mounted ametallic spheroid, 2, having a neck, 3, provided with a female thread,by which the connection is made, and having 'at its highest point aburner-tip, 4, mounted upon a disk, 5, which is tapped into a boss, 6,upon the spheroid 2, forming a removable cap, which may be utilized toobtain access to the interior.

A little in rear oi" the burner-'tip 4 is formed a boss, 7, into whichis tapped a vertical tube, 8, rising to a height of some inches abovethe top of the spherical shell 2.

From the neck 3, and from a point j ust above the stem l of thegas-bracket, a pipe, 9, rises, the lower open end thereof wholly closingthe opening between the interior of-the shell 2 and the neck 3. Thispipe is slightly curved to one side to bring it into the axial line ofthe vertical pipe 8, into which it enters and extends to a pointnear theupper closed end of said pipe, as shown in Fig. l. The pipe 9 is open.at both ends and constitutes the channel through which the gas mustpass as it tlows from the gas-supply pipe l, the diameter Serial No.205,793. (No'morlel.)

described, the gas is turned on at the bracket and lighted at theburner-tip 4. generated thereby is speedilymparted to the outer closedtube, 8, through which the gas passes after it leaves the pipe 9. Thegas heated thereby Hows down into the interior of the shell 2, where itis brought in contacty with the hydrocarboncontained therein, a`V

portion of which is volatilized by the heat and taken upY by or mingledwith the gas. The gas thus enriched is consumedv at the burner, givingan increased illumination with a less consumption of the gas from themain source of supply.

The other advantages of this invention are, that as but comparativelysmall quantities of hydrocarbon are used at any one point, there is notonly no danger of explosion, but the `complicated and costly apparatusfor the generation of the enriching gas is wholly avoided, makingagreatreduction in expense, and saving much time and labor. y

By turning the burner-tip until the slot in its end is directed towardthe standing pipe 8, the full heating-power of the llame may be di-lrected upon the said tube, whereas byffar ranging it slightly to oneside or theother, so that the flame shall not strike upon the pipe, theheating-power may be varied according to requirements.

rlhe shell containing the naphthaline may be of any form other thanspherical.

I am aware that it is not broadly new toV provide so-calledcarbureting-lampsl with means for heating gas prior to its entrance intoa vessel containing a hydrocarbon which is designed to be vaporized bythe heated gas in order to become mingled therewith and enrich the same.Lamps of this nature have been made in various ways with provisionfor anupward and downward passage ofthe gas in tubes contiguous to thegas-flame. not aware, however, that an apparatus of the `The heat IOOIam

construction herein described and claimed has hitherto been used,.lorthat a carburetingvessel has heretofore been provided at the top withconcentric gas-tubes projecting above said vessel, and with an adjacentrotatable plug that closes the illing-orice, and carries a burner-tip,which is thus capable of being turned toward or away from the concentricgas-tubes to vary the degree of heat thrown thereon. By my constructionI provide a device of great simplicity which is capable of thoroughlyheating the gas before it comes in contact with the hydrocarbon, andwhich enables the heating of the gas and consequent intensity of thelight to be controlled at will by simply turning the burner-tip withoutdiminishing or increasing the How of gas.

Having thus described my invention, what I claim is A carbureting gaslamp composed of a carscrew-neck through the carbureting-vesseland int'othe heating-tube, and the rotatable plug 5, and connected burner-tip 4,seated in the upper screw-neck and adapted to be turned to vary thedegree of heat thrown on the heating-tube, substantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
